HOSE-COUPLING.

SPEGIFIGATIQN forming part of Letters Patent No. 712,775, dated November4, 1902.

Application filed June 12, 1902. Seria No. 111,308. (No model.) 7

T0 00 whom it may concern.-

Beit known that LROBERT M. DIXON, a citizen of the United States, and aresident of East Orange, Essex county, New Jersey, have invented certainnew and useful Improvements in Hose-Couplers, of which the following isa specification.

My invention relates to hose-couplers; and it consists of the novelfeatures hereinafter set forth and claimed.

In the accompanying drawings I have shown one member of a hosecouplingin which myinvention is embodied, it being understood that thisconstruction is shown by way of illustration merely and that myinvention is not confined to the construction shown.

Figure I is a transverse section through the coupling. Fig. II isan endview thereof, and Fig. III is an isometric view of the removable sleeveor bushing.

In the drawings, (1 indicates the couplerhead, which is or may beprovided with any suitable means for engaging a companion coupler, so asto afford a passage for the uninterrupted flow of fluids. This head isrecessed interiorly, as at b, and is provided with an internalinterrupted shoulder composed of lugs c and the intervening grooves d. Aremovable bushing is provided, shown in the present instance ascomprising, a gasket e, of fibrous or-other material, mounted or moldedupon a metallic collar f, having an engaging flange g and anoutwardly-turned flange h, carrying lugs 'tj k,which are adapted toenter the grooves or recesses between the lugs c of the interruptedannular shoulder.

The lugs ij k are transversely slotted for the reception of alocking-spring Z, shown in the present instance as a wire having a bentend m, adapted to bear against the side of the lug i, and a hooked orhandled end 0, by which the spring may be slightly collapsed.

By referring to Fig. I it will be observed that when the removablebushing is in place the locking-spring will rest against the rear faces19 of the lugs c and will lock the bushing firmly in place in thecoupling. Removal of the bushing from the coupling may be accomplishedby engaging the hook or handle 0 and pulling the spring slightly toclear it of the faces 19. IV hen it is desired to reinsert the bushing,it is simply pressed back into place, the beveled faces q of the lugsserving to collapse the spring until the said spring passes the saidfacesand is expanded outwardly by its own resiliency to lock the bushingin place.

Having described my invention, what I claim, and desire to secure byLetters Patcut, is

1. In combination, a coupler-head provided with internal lugs,'aremovable bushing provided with lugs, and a locking-spring carried bythe lugs of the bushing and adapted to rest behind the lugs of thecoupler-head. to lock the bushing in place in the coupling.

2. In combination, a coupler-head provided with a shoulder, a luggedbushing and a locking-spring intervening between the lugs of the bushingand the logged portion of the coupler-head.
